Lore: I still can not fathom how Mamono not taking over the world with their capabilities as encyclopedia described them. They seems so OP, every last one of them, yet they still pretty much at war with human for some reason. Either Human is not as incompetent as book described, then mamono just spent everyday mating with male/husband without any real-long term goal.
Also, I found extremist monster faction to be "tasteless" in their tactics by using pleasure to corrupt everything, paint their own value to human and said it's "love and happiness"
For individual mamono, I guess nothing much because that's just subjective matters like "I don't like her design" or "Damn I don't like their husband hunting tactics" Maybe just like I said in lore part, they're all seems so OP and Mary Sue so it kind of breaking my immersion sometimes
Edit: I also like to add that, when everything in life suddenly becomes nothing but sex or sex related, it might be fun if you actually live there but it just numb down the excitement for reader since you can predict everything. There's no cost or stake so frankly, I kind of cheering human more than mamono at this rate. Well at least the good human and not piece of shit like Lescatie aristocrats. And no, there's no need to remind me that sex is the setting and fundamental of things. I know that, but it just boring.
